SAFETY-RAZOR.

Specification of Letters Patent.

Patented Feb. 1, 1916.

Application iiled August 2, 1915. Serial No 43,301.

- and contemplates, primarily, the provision of a safety razor which shall be of-simple and improved construction.

Another object of my invention is to provide a safety razor in which a cap or backing, a blade and a guard are so mounted ona handle asto be adjustable thereon as a unit to difi'erent angular positions relative thereto for the purpose of changing the cut ting angle of the blade with respectto the longitudinal axis of the handle. In other words, I provide a razor in which the operator may adjust the blade-holding means and handle relatively, so that preferring, or being accustomed to hold the handle of a razor in a certain position to obtain a certain cutting angle of the blade, he may, in order to hold the'razor as he desires, adju t the razor so as to obtain the desired cutting angle of the blade. 7

A further object is to provide a safety razor having means for detachably securing a back, a blade and a guard to a handle, which will permit the blade to be. quickly and easily inserted and removed from the blade-holding means.

My invention and its mode and principle of operation will become better understood by reference to the following description when considered in connection with the accompanying drawing, wherein Figure l is aside elevation of a safety razor embodying my improvements; Fig. 2 is a view, looking at the left hand side of the razor, as shown in Fig. 1; Fig. 3 is a cross-sectional view through the razor taken on the line 3'3 of Fig. 2; Fig. 4 is an enlarged-cross-sectional view through the cap or backing; and Fig.5 is a perspective view of a handle provided with a different form of cam surface at its inner end from that shown in Fig. 3. 7

Referring to the drawing, a cap or backing 6,. blade 7, guard 8 and handle 9, all

designated in general, comprise the main elements of my safety razor, all of which will be more particularly described hereinafter.

The cap or backing 6, having aslightly concave blade-receiving face 11, is provided The guard 8,

12, rests on the blade and is adapted to be clamped to the backing by means described hereinafter, so .as to fixedly secure the blade in operative position. It will be here noted that the blade is held flat so as not to be arched or bent, and consequently weakened at its central portion; that no members 01' parts project through the bla dc, backing, or guard for the purpose of locking these members together; and that the blade and guard are held'against endwise and sidewise displacement by the end portlons 12 of the backing. The backing is'provided at its corners with projecting guards 10 which overlie the corners'of the blade and, obviously, prevent scratching'or cutting while in use. I k

The means for clamping the guard and backing together and detachably and adjustably connecting these members to the handle will now be described. The handle 9 of suitable design, hassecured to its inner end a cross-bar comprising a pair of diametrically oppositely extending arms 14, the outer ends of which are reduced as at 15 and adapted to be pivotally mounted on the end portions 12 of the backing. For this purpose, one of the said ends 12 is provided centrally on its inner side with a circular socket 16 adapted to receive the end of one of the arms 14 so as to serve asa fixedpivot, and the other end 12 is provided with a groove l8 leading from the socket at an incline extending away from the blade-receiving face of the backing to the edge of the said end portion, as shown clearly in Fig. 4;.

similar socket l7 and also with a slot or" This groove permits the arm 14 opposite that in the fixed pivot socket'16 to be entered into socket 18 Without flexing or moving the arms pelgtively and at the sanae'tiin pro;

vides acamjface 19 for drawing the outer arm of the .cross-head toward the guard and backing While being moved to operative position. It will be noted that the width of the groove is slightly less than-the diameter of the socket 17 so that a shoulder 21 is formed adjacent to the socket for preeluding displacement of the adjacent end from the socket. v The handle is so constructed to cooperate with the guard and the sockets 16 and 18 so positioned that with a blade and guard properly mounted on the backing, when the handle has been attached to the backing, the

. cross-head of the handle by movement on the incline groove to the socket 17 will 1 slightly clamp the guard and blade to the blade-receiving'face of the backing. This. is effected by the inner end portion of the handle abutting against the guard and the action of the cam face 19 in moving the cross-head inwardly toward the guard. As will be seen by reference to Fig. 3, the saidinner end portion of the handle is shaped to at different distances from the axis of the arms 14, the adjoining faces 23 beingequi-v distant from said axis and a therefrom than the face 22.

When attaching the handle to the backing, the handle is positioned so that its face 22 lies adjacent to the guard'and its arms 14. may be easily entered on their pivots. When greater distance so assembling the razor,'itwil1 be noted that the backing will be disposed at an acute angle relative to the longitudinal axis of the handle. To securely lock the handle to the backing, clamp the guard thereto, and conseque'ntly lock the bladein operative'position, the handle should be turned on its pivots so' as to movethe .face 23 adjoining the face 22 into engagement with the guard, thus positioning the backing as indicated in dotted lines 24 on Fig. 1. It will be manifest that by moving the several parts to different positions, the guardwill have been clamped to the backing by the action of said face 23, the arms 14 flexing slightly and serving as a spring backing to permit the handle to turn beyond the high corners at the juncture of the cam faces 22 and 23 and to yieldingly but firmly hold the .parts .in associated, operativ position.

The safety razor may be used when the blade is thus positionedat right angles to the longtitudinal axis of the handle. Since many users prefer to-havethe blade positioned at an acute angle to said axis, the handle may be adjusted relatively toefi'ect .this object by moving the handle on its pivots until the second face-22 engages the guard as shown in Fig. 3. Manifestly, a series of faces 23 might be provided to hold angles.

the blade positively at different cutting To take up for wear between the faces 23 and the guard and to secure proper cooperation between these parts, 1 have provided the guardwith a hardened screw 25,

Fig. 3, against the head of which the faces 23 are adapted to abut. By adjusting the screw, it will be apparent that the tightening or clamping'eflect of the handle may be varied.

In Fig. 5, I have illustrated the handle as permitting the arms of the handle to be entered on their pivots. It-will be manifest that by turning the handle on its; pivots in either direction, the guard and the blade will be clamped to the backing and the handle'held securely in connection therewith. Also it will be apparent that the backing, blade and guard maybe adjusted as a unit about the pivot axis of a handle to any angular position desired, and that either of the cutting edges of the razor-may be employed, since the blade-holding means may be adjusted to operative positions on either side of the face 27.

It is believed that the foregoingwill con vey a clear understanding. of my invention, and it should be understood that changes in detail of construction might bemade without departing from the spirit and scope of.

the invention claims.

I

tween saidv end portions, a handle provided at one end with a cross-head, one of said" raised ends being formed on its innerf side with a recess and the other with a recess and a cam groove leading thereto, whereby the ends of the cross-head may be entered into the said recess to eflect pivotal attach- -ment of the handle to the blade-holding means, and cam means cooperative between the handle and blade-holding means for holding the latter in any of several different angular positions with respect to the handle,

several parts being effected by the said cam means when the blade-holding means and handle are adjusted relatively.
